Last time I checked, only the US and Israel. Europeans don't want anything to do with this war, and the USA's East Asian allies also like it not even a little bit.

As a Brit, I'm disgusted that Starmer is allowing UK bases to be used by the US for launching attacks. I can see it being just a matter of time before Starmer drags us into another war of lies. (Last time it was Tony Blair, also a Labour leader and he still hasn't been tried for his war crimes).
